SMOKE-CONSUMER.

SPECIFICATION forming part of LettersPatent No. 707,341, dated August 19, 1902.

Application filed May-24, 1902. Serial No. 108,808. (No model.)

To all whom it may concern:

Be it known that I, LEWIS E. MORGAL, a Cllll'. zen of .the United States, residing at Washington, District of Columbia, have invented certain new and useful Improvements in Smoke-Consumers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to smoke-consumers; and'it consists in the novel construction and arrangement of its parts, as hereinafter described.

The object of thisinvention is to provide a device for taking the smoke from a furnacestack and removing the cinders, soot, and other particles therefrom and delivering the smoke back into the stack or under the furnace-grate for reburning, as may be desired.

For separating the heavy particles from the smoke a jet of steam is turned into the smoke at a blower, and the smoke thus moistened is forced into a box, Where the heavy particles are separated and retained in the box.

In the accompanying drawings, Figure 1 is a side elevation of the smoke-consumer, partly in section. Fig. 2 is an end elevation ofthe smoke-consumer, partly in section.

The box 1 is arranged adjacent the boiler furnace 2, and a revolving fan 3 is located adjacent said box 1, said fan 3 bein g surrounded by a casing 4, the. peripheral outlet 5 of which is connected to the said box 1. The furnace-stack 6 is provided with a damper 7, and a pipe 8 connects the saidstack 6, at a .3 5 point below the said damper 7, with the center of the said casing 4. The steam-pipe 9 connects the boiler or other steam generator with the pipe 8, said pipe 9 being provided with a valve 10. The top of the box lis connected by means of the pipe 11 with the stack 6 ata point above the damper 7, said pipe 11 being provided with a damper12. The top of the box 1 is also connected by means of the pipe 13 with the ash-pit of the furnace 2, said pipe 13 being provided with the damper 14.

In the interior'of the box 1 is arranged a concaved diaphragm 15, the end of which is curved down at the point 16 and extends down at the point 17, parallel with the end of the said box and at a short distance from the same. The loosely-journaled fan 18 is arranged above the curved portion 16 of the diaphragm 15.

The operation of the device is as follows: In coaling the furnace the damper is closed and the fan 3 is set in rapid revolution. The draft thus created draws the smoke from the stack 6 through the pipe Sintothe fan-casing I box 1 against the under side of the concaved diaphragm 15. The cinders striking-against the under side of the said diaphragm are precipitated into the bottom of the box, while the gases and soot pass-around the end 17 of the diaphragm and are churned bythe revolution of the fan 18. This churning has a tendency to separate the soot and precipitate the same in the bottom of the box. From the top of the box 1 the smoke and steam may be conducted through the pipe 11 into the stack 6, above the damper 7, or by closing the damper 12 and opening the damper 14 the said smoke and steam may be conducted through the pipe 13 into the ash-pit and under the grate of the furnace 2, whereby a blast will be supplied the fire and the particles reburned.

The condensation of the steam that takes place in the pipe 11 and stack 6 runs down along the sides of said pipe and stack and washes any soot that collects against the said sides toward box 1 or the fire-box of the furnace 2.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A device of the character as described, consisting of a box, a concaved diaphragm located'in said box and being secured at one end and at its longitudinal edges to the inner sides of the box, and at its other end terminating at a distance from the inner sideof the box and leaving a space between the said end and the said inner sideof the box, a fan journaled at the end-of the diaphragm, and substantially filling the space between the end of the diaphragm and the inner side of the box, a means for introducing smoke below said diaphragm and a smoke-exit located above the said diaphragm.

2. A device of the character as described,

consisting of a box, a diaphragm located in said box, said diaphragm having at its end a downwardly-curved portion, a revolving fan located above said curved portion, said box having a smoke-entrance located below the diaphragm and a smoke-exit located above the diaphragm.

3. A device of the character as described,

consisting of a box, a diaphragm located in said box, said diaphragm having a downwardly-curved portion and a perpendicular end extending substantially parallel with the end of the box and at a distance from the said end, a revolving fan located above the downwardly-ourved portion of the diaphragm, said box having a smoke-entrance located below the diaphragm and smoke-exit located above the diaphragm.
